What does a site EUI of 266.5 kBtu/ft² mean?
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 1635 Poplar St.'s 266.5 kBtu/ft² across 27,600 sq ft works out to about 7.4 billion Btu (2,156 MWh-equivalent) in 2024. Its source EUI of 584.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,408,082 kWh of electricity, 25,522 therms of natural gas and 5,583 thousand gallons of water for the year.
